Projects/Summer of Code/2007/Projects/KAider

KAider is a computer-aided translation system that focuses on productivity and performance. Translator does only creative work (of delivering message in his/her mother language in laconic and easy to understand form). KAider implies parapgraph-by-paragrah translation approach (when translating documentation) and message-by-message approach (when translating GUI). See KAider/Introduction

Current state

Already has:

  • syntax highlighting
  • spellcheck (sonnet needs improvement)
  • search-n-replace, ignoring accel marks
  • formats .po file output better so less diff is generated by scripty
  • small features like quick tag insert, placing text cursor right after the tag in the beginning (e.g. '<qt>|foobar</qt>' where "|" is a cursor), entry bookmarks
  • viewer of the difference between current msgid and previous one (i.e. msgid translation of which current msgstr really is -- for fuzzies generated with --previous gettext option)
  • merge mode for editors (QA) or when several translators work on the same file screenshot
  • basic projectmanager functionality screenshot
  • Translation Memory (threaded) with shortcuts for inserting suggestions into current 'msgstr', scores are computed based on common/total length ratio, removed+added length, and count of removed+added parts screenshot
  • for difference representation in all places word-by-word algorithm is used (based on the Longest Common Sequence o(n*n) algorithm and my own experience)
  • glossary with basic tbx format support. KAider displays relevant entries on-the-fly and provides shortcuts to insert them. also, you can add new glossary terms via context menu of the glossary screenshot
  • webquery view, flexible thanks to kross
  • Search/Replace functions in multiple files at once.
  • Spellchecking of multiple files at once.


After you set kde env up (compiling kdelibs is enough):

cd trunk/extragear
svn up sdk
su kde-devel
mkdir sdk/kaider/build
cd sdk/kaider/build
cmakekde ..

as a root, run sshd and then from the usual shell:

ssh -XC [email protected]

you can get catalogmanager by specifying --project option

kaider --project /path/to/index.ktp

See http://websvn.kde.org/trunk/l10n-kde4/ru/


  • Majority of actions must be accessible via keyboard (because it is faster to press a shotcut than to be frustrated with a mouse)
  • Do automatization _everywhere_ it possible
  • Focus on quality. This is open source -- so source code is available (for change)

Further work

  • dbus
  • WebQuery for twin languages (like ukrainian and russian)
  • xliff+qt-linguist support (see KBabel features to be implemented)
  • Automatic Glossary building
  • Research on dividing into sentences rules (e.g. srx)
  • project-wise and program-wise: webquery scripts, glossaries, TMs
  • Glossary checklists: check for forbidden terms in new translation
  • Tighten SVN support: svn diff-like feature
  • Automate submitting translation suggestions to translate.google.com [Kross action]
  • back-checking, to see whether a term/string in the target language has been used as translation for different things, not just that one source has the same translation everywhere.
  • [Kross (project) action] that merges translations with updated template
  • fill TM with content of /usr/share/locale/<lang>/LC_MESSAGES/*.mo [Kross action]

Not for KDE:

  • Be complete computer-aided translation system by providing e.g. actions to import+export openoffice, txt and documents of other formats by calling appropriate scripts/commands. Define for that general kross actions interface.
  • Make nice windoze package for the windowzerz

Competitors (ideas):

Converters (use, acting as a front-end):

KBabel features to be implemented

...in a smarter way :). After or during the summer.

  • persistent bookmarks for messages in a file saved in the project
  • extended marking of .po and .pot files (e.g. translator that currently works on the file and cince when) saved in the project
  • Opening source code by references in message comments [Kross action]
  • A plugin framework for validation tools for consistency checks [Kross action triggered on saving]
  • Sending the file using email [Kross (project) action]
  • Automatic syntax check with msgfmt when saving and, if an error occured, easy navigation to messages, which contain errors. == Syntax check (msgfmt --statistics) for existing files to control if the translated files will compile and, accordingly, work when distributed [Kross (project) action]
  • CVS and SVN support [Kross project action] (is 'svn ci' so hard?)
  • statistics
  • PO File Header change [Kross action (+triggered on saving)]
  • Printing of selected messages (eg fuzzy ) [Kross action]


  • msgid-diff-msgstr from [2] (features for all other commands are already implemented, if you haven't noticed this)

KBabel features NOT to be implemented

  • Character selection tool integration, sort by the frequency

Why? Better improve system-wide charselect tool, OR... modify your xorg keyboard layout!


  • Create project, saving *.ktp file to l10n-kde4/<LangCode>
  • Populate Glossary via GlossaryView context menu (.tbx file will be created automatically for you on the first entry addition).
  • Populate Translation Memory by dropping .po files onto TM View
